Petunia plant named ‘Duesurimrovein’

ABSTRACT

A new and distinct cultivar of Petunia plant named ‘Duesurimrovein’, characterized by its upright and outwardly spreading plant habit; freely basal branching; and single flowers that are dark pink in color with red purple-colored venation.

BOTANICAL CLASSIFICATION/CULTIVAR DESIGNATION

Petunia×hybrida cultivar Duesurimrovein.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida, and hereinafter referred to by the cultivar name Duesurimrovein.

The new Petunia is a product of a planned breeding program conducted by the Inventor in Rheinberg, Germany. The objective of the breeding program is to create new freely branching Petunias with large flowers and attractive flower coloration.

The new Petunia originated from a cross pollination made by the Inventor in 1997 of a proprietary Petunia selection identified as code number 94-211, not patented, as the female, or seed parent, with a proprietary Petunia selection identified as code number F-18-22, not patented, as the male, or pollen parent. The new Petunia was selected as a single plant from the resulting progeny by the Inventor in Rheinberg, Germany in 1998, on the basis of its attractive flower color.

Asexual reproduction of the new cultivar by terminal vegetative cuttings taken in Rheinberg, Germany since 1999, has shown that the unique features of this new Petunia are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Duesurimrovein have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Duesurimrovein’. These characteristics in combination distinguish ‘Duesurimrovein’ as a new and distinct cultivar:

1. Upright and outwardly spreading plant habit.

2. Freely basal branching.

3. Single flowers that are dark pink in color with red purple-colored venation.

Compared to plants of the female parent, the selection 94-211, plants of the new Petunia have larger flowers and differ in flower color. Compared to plants of the male parent, the selection F- 18-22, plants of the new Petunia have larger flowers and differ in flower color.

Plants of the new Petunia can be compared to plants of the cultivar Surfinia Pink Vein, not patented. In side-by-side comparisons conducted in Rheinberg, Germany, plants of the new Petunia differed from plants of the cultivar Surfinia Pink Vein in the following characteristics:

1. Plants of the new Petunia had longer internodes than plants of the cultivar Surfinia Pink Vein.

2. Plants of the new Petunia had larger leaves with longer petioles than plants of the cultivar Surfinia Pink Vein.

3 . Plants of the new Petunia had larger flowers than plants of the cultivar Surfinia Pink Vein.

4. Flowers of plants of the new Petunia were darker in color than flowers of plants of the cultivar Surfinia Pink Vein.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Petunia.

The photograph comprises a top perspective view of typical flowers and leaves of ‘Duesurimrovein’.

DETAILED BOTANICAL DESCRIPTION

The cultivar Duesurimrovein has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature and light intensity without, however, any variance in genotype.

The aforementioned photographs, following observations and measurements describe plants grown during the spring in Rheinberg, Germany, under commercial practice in a glass-covered greenhouse. Plants were about 16 weeks from cuttings and were grown in containers. During the production of the plants, day and night temperatures averaged 18° C. and light levels were about 4,500 lux. Plants were pinched once about three weeks after planting.

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
